User login list on lightdm managed desktop

Post by bobinmurphy »

I have 18.3 on my system and installed libvirt-manager. It created a couple of entires in the passwd file for accounts libvirt-qemu and libvirt-dnsmasq. Both entires have UID and GID values outside the range used for login as defined in the /etc/login.defs file. However there's always and entry on the lightdm login screen for the libvirt-qemu entry. Neither account is a user account that can be logged into. How do I get the libvirt-qemu entry removed from the list of users on the login page?

You could try replacing lightdm with mdm:

sudo apt install mdm xscreensaver

sudo apt remove slick-greeter lightdm lightdm-settings apparmor

/etc/lightdm/users.conf has a [UserList] option 'minmum-uid=500' which looks to conflict with /etc/login.defs 'UID_MIN 1000'.
You could try setting minimum-uid=1000 and see if that helps. Your user id should = 1000. typing 'id' at the command prompt will tell.

Regardless of the conflicts between /etc/lightdm/users.conf and /etc/login.defs for the min and max UID and GID, the values for libvirt-qemu are GID=64055 and UID=131. If either of the config files were actually controlling which "users" are presented for login, libvirt-qemu shouldn't show up.
